It looks like multiple items in deploying the "enterprise edition" have licenses and are actually a closed-source model.
To me this looks like a flashy web page that makes all the right noises about "data sovereignty", etc, but relies (on the actual back-end) on multiple providers who have in fact cut off access to code; they even take pains to say it is "less than x% of code" or "Admin Console container image: 100% closed source", etc.
There are multiple examples on that page.
